From GeekZone Bluepulse works with Bluetooth and cell networks
Bluepulse is an application for mobile phones which allows a person to access information based on their surroundings.
For example, in a shopping centre, it will help users find a particular shop or an ATM or toilet with step-by-step directions automatically appearing. You can then check to see outside which shop a friend or relative is located, view available shop specials in the centre from any location, check the movie times, look at movie trailers and even have your shopping list appear from your home computer.
The company says the software is faster and easier than WAP, including caching, using the phone's UI to speed rendering, and allowing the users to install new bluepulse apps from desktop browser as well as from the phone
